Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Significant Accounting Policies	NOTE 1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES Organization and Business Description Bimini Capital Management, Inc., a Maryland corporation (“Bimini Capital”), was formed in September 2003 for the purpose of creating and managing a leveraged investment portfolio consisting of residential mortgage-backed securities (“MBS”). Bimini Capital has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”). As a REIT, Bimini Capital is generally not subject to federal income tax on its REIT taxable income provided that it distributes to its stockholders at least 90% of its REIT taxable income on an annual basis. In addition, a REIT must meet other provisions of the Code to retain its special tax status. Bimini Capital's website is located at http://www.biminicapital.com. On November 3, 2005, Bimini Capital acquired Opteum Financial Services, LLC (“OFS”), and at closing, OFS became a wholly-owned taxable REIT subsidiary (or “TRS”) of Bimini Capital. OFS was renamed Orchid Island TRS, LLC (“OITRS”) effective July 3, 2007 and then renamed MortCo TRS, LLC (“MortCo”) effective March 8, 2011. Hereinafter, any historical mention, discussion or references to Opteum Financial Services, LLC, Orchid Island TRS, LLC, OFS or to OITRS (such as in previously filed documents or Exhibits) now means MortCo. As used in this document, discussions related to “Bimini Capital,” the parent company, the registrant, and to REIT qualifying activities or the general management of Bimini Capital's portfolio of MBS refer to Bimini Capital Management, Inc. and its wholly-owned qualified REIT subsidiary, Orchid Island Capital, Inc. (“Orchid”). Discussions related to Bimini Capital's taxable REIT subsidiaries or non-REIT eligible assets refer to Bimini Advisors, Inc. and its wholly owned subsidiary, Bimini Advisors, LLC (together “Bimini Advisors”) and MortCo and its consolidated subsidiaries. Discussions relating to “the Company” refer to the consolidated entity. Liquidity Material losses incurred by the Company in 2006 and 2007 attributable to the former mortgage origination operations of MortCo have significantly reduced Bimini Capital's equity capital base and the size of its MBS portfolio when compared to pre-2006 levels. Ongoing litigation costs stemming from both the former operations of MortCo and Bimini Capital itself have caused the Company's overhead to be high in relation to its portfolio size. The smaller capital base makes it difficult to generate sufficient net interest income to cover expenses. In response, beginning in 2007, the Company took significant steps to reduce the leverage in its balance sheet, reduce its debt service costs, reduce expenses, settle various litigation matters, and alter its investment strategy for holding MBS securities. In addition, the Company continued to evaluate capital raising opportunities for Orchid, its wholly-owned subsidiary. After pursuing previous efforts to raise capital at Orchid, Orchid completed an initial public offering of common stock on February 20, 2013. The Company acted as sponsor to Orchid by agreeing to fund all underwriting, legal and other costs of the offering. In addition, until Orchid has $100 million of stockholders equity, the Company will not allocate any overhead costs to Orchid that it would be able to do otherwise. Attracting external capital to Orchid will allow the Company to receive fees for managing the Orchid portfolio, decrease the Company's expenses by allocating certain overhead costs to Orchid (once Orchid's stockholders' equity exceeds $100 million), and share in distributions, if any, paid by Orchid to its shareholders. Upon closing of Orchid's initial public offering, the Company owned approximately 29.38% of the outstanding common stock of Orchid. At December 31, 2012, Bimini Capital had cash and cash equivalents of $6.6 million, an equity capital base of $3.5 million and an MBS portfolio of $168.2 million. The Company generated cash flows of $23.1 million from principal and interest payments on its MBS portfolio and $4.5 million from retained interests in securitizations during the year ended December 31, 2012. However, if cash resources are, at any time, insufficient to satisfy the Company's liquidity requirements, such as when cash flow from operations are materially negative, the Company may be required to pledge additional assets to meet margin calls, liquidate assets, sell additional debt or equity securities or pursue other financing alternatives. Basis of Presentation The accompanying consolidated financial statements are prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“GAAP”). In the opinion of management, all adjustments considered necessary for a fair presentation of the Company's consolidated financial position, results of operations and cash flows have been included and are of a normal and recurring nature. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates affecting the accompanying financial statements include the fair values of MBS, Eurodollar futures contracts, retained interests and asset valuation allowances. Consolidation The accompanying consolidated financial statements include the accounts of Bimini Capital and its wholly-owned subsidiaries, Orchid, Bimini Advisors and MortCo, as well as the wholly-owned subsidiaries of MortCo. All inter-company accounts and transactions have been eliminated from the consolidated financial statements. As further described in Note 8, Bimini Capital has a common share investment in a trust used in connection with the issuance of Bimini Capital's junior subordinated notes. Pursuant to the applicable accounting guidance for variable interest entities, Bimini Capital's common share investment in the trust has not been consolidated in the financial statements of Bimini Capital, and accordingly, this investment has been accounted for on the equity method. Statement of Comprehensive Income (Loss) In accordance with FASB ASC Topic 220, Comprehensive Income, a statement of comprehensive income has not been included as the Company has no items of other comprehensive income. Comprehensive loss is the same as net loss for all periods presented. Cash and Cash Equivalents and Restricted Cash Cash and cash equivalents include cash on deposit with financial institutions and highly liquid investments with original maturities of three months or less. Restricted cash represents cash held on deposit as collateral with the repurchase agreement counterparties, which may be used to make principal and interest payments on the related repurchase agreements, and cash held by a broker as margin on Eurodollar futures contracts. Cash and cash equivalents are maintained at financial institutions and, at times, balances may exceed federally insured limits. The Company has never experienced any losses related to these balances. All noninterest-bearing cash balances were fully insured at December 31, 2012 due to a temporary federal program in effect from December 31, 2010 through December 31, 2012. Under the program, there is no limit to the amount of insurance for eligible accounts. Beginning in 2013, insurance coverage will revert to $250,000 per depositor at each financial institution, and the Company's noninterest-bearing cash balances may again exceed federally insured limits. Interest-bearing amounts on deposit that would have been in excess of the $250,000 federally insured limit at December 31, 2012 approximated $3.5 million. Mortgage-Backed Securities The Company invests primarily in pass-through (“PT”) mortgage-backed securities (“MBS”), collateralized mortgage obligations, interest only (“IO”) securities and inverse interest only (“IIO”) securities representing interest in or obligations backed by pools of mortgage loans (collectively, MBS). MBS transactions are recorded on the trade date. The Company has elected to account for its investment in MBS under the fair value option. These investments meet the requirements to be classified as available for sale under ASC 320-10-25, Debt and Equity Securities, which requires the securities to be carried at fair value on the Consolidated Balance Sheet with changes in fair value charged to Other Comprehensive Income, a component of Stockholders' Equity. Electing the fair value option allows the Company to record changes in fair value in the Statement of Operations, which, in management's view, more appropriately reflects the results of our operations for a particular reporting period and is consistent with the underlying economics and how the portfolio is managed. The fair value of the Company's investment in MBS is governed by FASB ASC Topic 820, Fair Value Measurement. The definition of fair value in FASB ASC Topic 820 focuses on the price that would be received to sell the asset or paid to transfer the liability in an orderly transaction between market participants at the measurement date. The fair value measurement assumes that the transaction to sell the asset or transfer the liability either occurs in the principal market for the asset or liability, or in the absence of a principal market, occurs in the most advantageous market for the asset or liability. Estimated fair values for MBS are based on the average of third-party broker quotes received and/or independent pricing sources when available. Income on PT MBS is based on the stated interest rate of the security. Premiums or discounts present at the date of purchase are not amortized. For interest only securities, the income is accrued based on the carrying value and the effective yield. Cash received is first applied to accrued interest and then to reduce the carrying value. At each reporting date, the effective yield is adjusted prospectively from the reporting period based on the new estimate of prepayments and the contractual terms of the security. For IIO securities, effective yield and income recognition calculations also take into account the index value applicable to the security. Changes is fair value of MBS during each reporting period are recorded in earnings and reported as unrealized gains and losses on mortgage-backed securities in the accompanying consolidated statements of operations. Retained Interests in Securitizations From 2005 to 2007, MortCo participated in securitization transactions as part of its mortgage origination business. Retained interests in the subordinated tranches of securities created in securitization transactions were initially recorded at their fair value when issued by MortCo. Subsequent adjustments to fair value are reflected in earnings. Quoted market prices for these assets are generally not available, so the Company estimates fair value based on the present value of expected future cash flows using management's best estimates of key assumptions, which include expected credit losses, prepayment speeds, weighted-average life, and discount rates commensurate with the inherent risks of the asset. Derivative Financial Instruments The Company has entered into derivative financial instruments to manage interest rate risk, facilitate asset/liability strategies, and manage other exposures, and it may continue to do so in the future. The Company has elected to not treat any of its derivative financial instruments as hedges. FASB ASC Topic 815, Derivatives and Hedging, requires that all derivative investments be carried at fair value. Changes in fair value are recorded in earnings for each period. Financial Instruments FASB ASC Topic 825, Financial Instruments, requires disclosure of the fair value of financial instruments for which it is practicable to estimate that value, either in the body of the financial statements or in the accompanying notes. MBS, Eurodollar futures contracts, mortgage loans held for sale and retained interests in securitization transactions are accounted for at fair value in the consolidated balance sheets. The methods and assumptions used to estimate fair value for these instruments are presented in Note 15 of the financial statements. The estimated fair value of cash and cash equivalents, restricted cash, accrued interest receivable, repurchase agreements, accrued interest payable and accounts payable and other liabilities generally approximates their carrying value as of December 31, 2012 and December 31, 2011, due to the short-term nature of these financial instruments. It is impractical to estimate the fair value of the Company's junior subordinated notes. Currently, there is a limited market for these types of instruments and the Company is unable to ascertain what interest rates would be available to the Company for similar financial instruments. Information regarding carrying amount, effective interest rate and maturity date for these instruments is presented in Note 8 to the financial statements. Property and Equipment, net Property and equipment, net, consists of computer equipment with a depreciable life of 3 years, office furniture and equipment with depreciable lives of 8 to 20 years, land which has no depreciable life, and buildings and improvements with depreciable lives of 30 years. Property and equipment is recorded at acquisition cost and depreciated using the straight-line method over the estimated useful lives of the assets. Repurchase Agreements The Company finances the acquisition of its PT MBS through the use of repurchase agreements. Repurchase agreements are treated as collateralized financing transactions and are carried at their contractual amounts, including accrued interest, as specified in the respective agreements. Although structured as a sale and repurchase obligation, a repurchase agreement operates as a financing under which securities are pledged as collateral to secure a short-term loan equal in value to a specified percentage (generally between 92 and 95 percent) of the market value of the pledged collateral. While used as collateral, the borrower retains beneficial ownership of the pledged collateral, including the right to distributions. At the maturity of a repurchase agreement, the borrower is required to repay the loan and concurrently receive the pledged collateral from the lender or, with the consent of the lender, renew such agreement at the then prevailing financing rate. Margin calls, whereby a lender requires that the Company pledge additional securities or cash as collateral to secure borrowings under its repurchase agreements with such a lender, are routinely experienced by the Company when the value of the MBS pledged as collateral declines or as a result of principal amortization or due to changes in market interest rates, spreads or other market conditions. The Company's repurchase agreements typically have terms ranging from one month to six months at inception, with some having longer terms. Should a counterparty decide not to renew a repurchase agreement at maturity, the Company must either refinance with another lender or be in a position to satisfy the obligation. If, during the term of a repurchase agreement, a lender should file for bankruptcy, the Company might experience difficulty recovering its pledged assets which could result in an unsecured claim against the lender for the difference between the amount loaned to the Company plus interest due to the counterparty and the fair value of the collateral pledged to such lender including accrued interest and cash posted as collateral. At December 31, 2012, the Company had outstanding balances under repurchase agreements with six lenders with a maximum amount at risk (the difference between the amount loaned to the Company, including interest payable, and the fair value of the collateral pledged by the Company, including accrued interest and cash posted as collateral) of $9.0 million. Share-Based Compensation The Company follows the provisions of FASB ASC Topic 718, Compensation – Stock Compensation, to account for stock and stock-based awards. For stock and stock-based awards issued to employees, a compensation charge is recorded against earnings over the vesting period based on the fair value of the award. Payments pursuant to dividend equivalent rights, which are granted along with certain equity based awards, are charged to stockholders' equity when declared. The Company applies a zero forfeiture rate for its equity based awards, as such awards have been granted to a limited number of employees and historical forfeitures have been minimal. A significant forfeiture, or an indication that significant forfeitures may occur, would result in a revised forfeiture rate which would be accounted for prospectively as a change in an estimate. For transactions with non-employees in which services are performed in exchange for the Company's common stock or other equity instruments, the transactions are recorded on the basis of the fair value of the service received or the fair value of the equity instruments issued, whichever is more readily measurable at the date of issuance. Earnings Per Share The Company follows the provisions of FASB ASC Topic 260, Earnings Per Share, which requires companies with complex capital structures, common stock equivalents or two (or more) classes of securities that participate in the declared dividends to present both basic and diluted earnings per share (“EPS”) on the face of the consolidated statement of operations. Basic EPS is calculated as income available to common stockholders divided by the weighted average number of common shares outstanding during the period. Diluted EPS is calculated using the “if converted” method for common stock equivalents. However, the common stock equivalents are not included in computing diluted EPS if the result is anti-dilutive. Outstanding shares of Class B Common Stock, participating and convertible into Class A Common Stock, are entitled to receive dividends in an amount equal to the dividends declared on each share of Class A Common Stock if, as and when authorized and declared by the Board of Directors. Accordingly, shares of the Class B Common Stock are included in the computation of basic EPS using the two-class method and, consequently, are presented separately from Class A Common Stock. The shares of Class C Common Stock are not included in the basic EPS computation as these shares do not have participation rights. The outstanding shares of Class B and Class C Common Stock are not included in the computation of diluted EPS for the Class A Common Stock as the conditions for conversion into shares of Class A Common Stock were not met. Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentations. Income Taxes Bimini Capital, including its wholly-owned qualified REIT subsidiary, has elected to be taxed as a REIT under the Code. Bimini Capital will generally not be subject to federal income tax on its REIT taxable income to the extent that Bimini Capital distributes its REIT taxable income to its stockholders and satisfies the ongoing REIT requirements, including meeting certain asset, income and stock ownership tests. A REIT must generally distribute at least 90% of its REIT taxable income to its stockholders, of which 85% generally must be distributed within the taxable year, in order to avoid the imposition of an excise tax. The remaining balance may be distributed up to the end of the following taxable year, provided the REIT elects to treat such amount as a prior year distribution and meets certain other requirements. At December 31, 2012, management believes that the Company has complied with Code requirements and Bimini Capital and its qualified REIT subsidiary continue to qualify as a REIT. As further described in Note 13, Income Taxes, Bimini Advisors and MortCo are taxpaying entities for income tax purposes and are taxed separately from the REIT. The Company's U.S. federal income tax returns for years ending on or after December 31, 2009 remain open for examination. Although management believes its calculations for tax returns are correct and the positions taken thereon are reasonable, the final outcome of tax audits could be materially different from the tax returns filed by the Company, and those differences could result in significant costs or benefits to the Company. Recent Accounting Pronouncements In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-04, Liabilities (Topic 405) - Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date ("ASU 2013-04"). The objective of the amendments in this update is to provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, except for obligations addressed within existing US GAAP. The amendments in ASU 2013-04 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, and should be retrospectively applied to all prior periods presented for those obligations resulting from joint and several liability arrangements within the ASU's scope that exist at the beginning of an entity's fiscal year of adoption. Early adoption is permitted. The Company does not expect that this ASU will have a material impact on its consolidated financial statements. In January 2013, FASB released ASU 2013-01 Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities, which served solely to clarify the scope of financial instruments included in ASU 2011-11 as there was concern about diversity in practice. The objectives of ASU 2013-01 and ASU 2011-11 are to support further convergence of US GAAP and IFRS requirements. These updates are effective for annual reporting periods beginning on or after January 1, 2013. The Company anticipates that the adoption of this ASU will have no effect on its consolidated financial statements. In December 2011, the FASB issued ASU 2011-11, Disclosures about Offsetting Assets and Liabilities, requiring improved information about financial instruments and derivative instruments that are either (1) offset in accordance with ASC 210-20-45 or ASC 815-10-45 or (2) subject to an enforceable master netting arrangement. This information will enable users of an entity's financial statements to evaluate the effect or potential effect of netting arrangements on an entity's financial position, including the effect or potential effect of rights of setoff associated with certain financial instruments and derivative instruments in the scope of this ASU. The Company is required to apply the amendments for annual periods beginning on or after January 1, 2013, and interim periods within those annual periods. The disclosures required will be provided retrospectively for all comparative periods presented. The Company anticipates that the adoption of this ASU will have no effect on its consolidated financial statements. In October 2011, the FASB issued a proposed ASU 2011-20, Financial Services-Investment Companies: Amendments to the Scope, Measurement, and Disclosure Requirements, which would amend the criteria in Topic 946 for determining whether an entity qualifies as an investment company for reporting purposes. As proposed, this ASU would affect the measurement, presentation and disclosure requirements for Investment Companies, as defined, amend the investment company definition in ASC 946, and remove the current exemption for Real Estate Investment Trusts from this topic. If promulgated in its current form, this proposal may result in a material modification to the presentation of the Company's consolidated financial statements. On December 12, 2012, the FASB agreed that the accounting for real estate investments should be considered in a second phase of the Investment Companies project and that all REITs should be exempted from conclusions reached in phase I of the project. The Board has not yet agreed on the scope of phase II of the project. The Company is monitoring developments related to this proposal and is evaluating the effects it would have on the Company's consolidated financial statements. In June 2011, the FASB issued ASU 2011-05, Presentation of Comprehensive Income, amending the authoritative guidance to allow an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. This ASU eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity, but does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The provisions of this amendment require retrospective application, and are effective for annual and interim periods beginning after December 15, 2011. The adoption of this ASU had no effect on the Company's consolidated financial statements, as the Company has no items of other comprehensive income. In May 2011, the FASB issued ASU 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, further converging U.S. GAAP and International Financial Reporting Standards (IFRS). The ASU changes the wording used to describe many of the requirements in GAAP for measuring fair value and for disclosing information about fair value measurements to ensure consistency between GAAP and IFRSs as well as expand the disclosures for Level 3 measurements. The ASU is to be applied prospectively, and is effective for annual and interim periods beginning after December 15, 2011. The adoption of this ASU had no effect on the Company's consolidated financial statements. In April 2011, the FASB issued ASU 2011-03, Reconsideration of Effective Control for Repurchase Agreements, which changes the assessment of whether repurchase agreement transactions should be accounted for as sales or secured financings. In a typical repurchase agreement transaction, an entity transfers financial assets to the counterparty in exchange for cash with an agreement for the counterparty to return the same or equivalent financial assets for a fixed price in the future. Prior to this ASU, one of the factors in determining whether sale treatment could be used was whether the transferor maintained effective control of the transferred assets and in order to do so, the transferor must have the ability to repurchase such assets. Based on this ASU, the FASB concluded that the assessment of effective control should focus on a transferor's contractual rights and obligations with respect to transferred financial assets, rather than whether the transferor has the practical ability to perform in accordance with those rights or obligations. Therefore, this ASU removes the transferor's ability to perform criterion from consideration of effective control. This ASU is effective for the first interim or annual period beginning on or after December 15, 2011. Since the Company records repurchase agreements as secured borrowings and not sales, the adoption of this ASU had no effect on the Company's consolidated financial statements.

Organization and Significant Accounting Policies

NOTE 1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Organization and Business Description

Bimini Capital Management, Inc., a Maryland corporation (“Bimini Capital”), was formed in September 2003 for the purpose of creating and managing a leveraged investment portfolio consisting of residential mortgage-backed securities (“MBS”). Bimini Capital has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”). As a REIT, Bimini Capital is generally not subject to federal income tax on its REIT taxable income provided that it distributes to its stockholders at least 90% of its REIT taxable income on an annual basis. In addition, a REIT must meet other provisions of the Code to retain its special tax status. Bimini Capital's website is located at http://www.biminicapital.com.

On November 3, 2005, Bimini Capital acquired Opteum Financial Services, LLC (“OFS”), and at closing, OFS became a wholly-owned taxable REIT subsidiary (or “TRS”) of Bimini Capital. OFS was renamed Orchid Island TRS, LLC (“OITRS”) effective July 3, 2007 and then renamed MortCo TRS, LLC (“MortCo”) effective March 8, 2011. Hereinafter, any historical mention, discussion or references to Opteum Financial Services, LLC, Orchid Island TRS, LLC, OFS or to OITRS (such as in previously filed documents or Exhibits) now means MortCo.

As used in this document, discussions related to “Bimini Capital,” the parent company, the registrant, and to REIT qualifying activities or the general management of Bimini Capital's portfolio of MBS refer to Bimini Capital Management, Inc. and its wholly-owned qualified REIT subsidiary, Orchid Island Capital, Inc. (“Orchid”). Discussions related to Bimini Capital's taxable REIT subsidiaries or non-REIT eligible assets refer to Bimini Advisors, Inc. and its wholly owned subsidiary, Bimini Advisors, LLC (together “Bimini Advisors”) and MortCo and its consolidated subsidiaries. Discussions relating to “the Company” refer to the consolidated entity.

Liquidity

Material losses incurred by the Company in 2006 and 2007 attributable to the former mortgage origination operations of MortCo have significantly reduced Bimini Capital's equity capital base and the size of its MBS portfolio when compared to pre-2006 levels. Ongoing litigation costs stemming from both the former operations of MortCo and Bimini Capital itself have caused the Company's overhead to be high in relation to its portfolio size. The smaller capital base makes it difficult to generate sufficient net interest income to cover expenses.

In response, beginning in 2007, the Company took significant steps to reduce the leverage in its balance sheet, reduce its debt service costs, reduce expenses, settle various litigation matters, and alter its investment strategy for holding MBS securities. In addition, the Company continued to evaluate capital raising opportunities for Orchid, its wholly-owned subsidiary. After pursuing previous efforts to raise capital at Orchid, Orchid completed an initial public offering of common stock on February 20, 2013. The Company acted as sponsor to Orchid by agreeing to fund all underwriting, legal and other costs of the offering. In addition, until Orchid has $100 million of stockholders equity, the Company will not allocate any overhead costs to Orchid that it would be able to do otherwise. Attracting external capital to Orchid will allow the Company to receive fees for managing the Orchid portfolio, decrease the Company's expenses by allocating certain overhead costs to Orchid (once Orchid's stockholders' equity exceeds $100 million), and share in distributions, if any, paid by Orchid to its shareholders. Upon closing of Orchid's initial public offering, the Company owned approximately 29.38% of the outstanding common stock of Orchid.

At December 31, 2012, Bimini Capital had cash and cash equivalents of $6.6 million, an equity capital base of $3.5 million and an MBS portfolio of $168.2 million. The Company generated cash flows of $23.1 million from principal and interest payments on its MBS portfolio and $4.5 million from retained interests in securitizations during the year ended December 31, 2012. However, if cash resources are, at any time, insufficient to satisfy the Company's liquidity requirements, such as when cash flow from operations are materially negative, the Company may be required to pledge additional assets to meet margin calls, liquidate assets, sell additional debt or equity securities or pursue other financing alternatives.

Basis of Presentation

The accompanying consolidated financial statements are prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“GAAP”). In the opinion of management, all adjustments considered necessary for a fair presentation of the Company's consolidated financial position, results of operations and cash flows have been included and are of a normal and recurring nature.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates affecting the accompanying financial statements include the fair values of MBS, Eurodollar futures contracts, retained interests and asset valuation allowances.

Consolidation

The accompanying consolidated financial statements include the accounts of Bimini Capital and its wholly-owned subsidiaries, Orchid, Bimini Advisors and MortCo, as well as the wholly-owned subsidiaries of MortCo. All inter-company accounts and transactions have been eliminated from the consolidated financial statements.

As further described in Note 8, Bimini Capital has a common share investment in a trust used in connection with the issuance of Bimini Capital's junior subordinated notes. Pursuant to the applicable accounting guidance for variable interest entities, Bimini Capital's common share investment in the trust has not been consolidated in the financial statements of Bimini Capital, and accordingly, this investment has been accounted for on the equity method.

Statement of Comprehensive Income (Loss)

In accordance with FASB ASC Topic 220, Comprehensive Income, a statement of comprehensive income has not been included as the Company has no items of other comprehensive income. Comprehensive loss is the same as net loss for all periods presented.

Cash and Cash Equivalents and Restricted Cash

Cash and cash equivalents include cash on deposit with financial institutions and highly liquid investments with original maturities of three months or less. Restricted cash represents cash held on deposit as collateral with the repurchase agreement counterparties, which may be used to make principal and interest payments on the related repurchase agreements, and cash held by a broker as margin on Eurodollar futures contracts.

Cash and cash equivalents are maintained at financial institutions and, at times, balances may exceed federally insured limits. The Company has never experienced any losses related to these balances. All noninterest-bearing cash balances were fully insured at December 31, 2012 due to a temporary federal program in effect from December 31, 2010 through December 31, 2012. Under the program, there is no limit to the amount of insurance for eligible accounts. Beginning in 2013, insurance coverage will revert to $250,000 per depositor at each financial institution, and the Company's noninterest-bearing cash balances may again exceed federally insured limits. Interest-bearing amounts on deposit that would have been in excess of the $250,000 federally insured limit at December 31, 2012 approximated $3.5 million.

Mortgage-Backed Securities

The Company invests primarily in pass-through (“PT”) mortgage-backed securities (“MBS”), collateralized mortgage obligations, interest only (“IO”) securities and inverse interest only (“IIO”) securities representing interest in or obligations backed by pools of mortgage loans (collectively, MBS). MBS transactions are recorded on the trade date. The Company has elected to account for its investment in MBS under the fair value option. These investments meet the requirements to be classified as available for sale under ASC 320-10-25, Debt and Equity Securities, which requires the securities to be carried at fair value on the Consolidated Balance Sheet with changes in fair value charged to Other Comprehensive Income, a component of Stockholders' Equity. Electing the fair value option allows the Company to record changes in fair value in the Statement of Operations, which, in management's view, more appropriately reflects the results of our operations for a particular reporting period and is consistent with the underlying economics and how the portfolio is managed.

The fair value of the Company's investment in MBS is governed by FASB ASC Topic 820, Fair Value Measurement. The definition of fair value in FASB ASC Topic 820 focuses on the price that would be received to sell the asset or paid to transfer the liability in an orderly transaction between market participants at the measurement date. The fair value measurement assumes that the transaction to sell the asset or transfer the liability either occurs in the principal market for the asset or liability, or in the absence of a principal market, occurs in the most advantageous market for the asset or liability. Estimated fair values for MBS are based on the average of third-party broker quotes received and/or independent pricing sources when available.

Income on PT MBS is based on the stated interest rate of the security. Premiums or discounts present at the date of purchase are not amortized. For interest only securities, the income is accrued based on the carrying value and the effective yield. Cash received is first applied to accrued interest and then to reduce the carrying value. At each reporting date, the effective yield is adjusted prospectively from the reporting period based on the new estimate of prepayments and the contractual terms of the security. For IIO securities, effective yield and income recognition calculations also take into account the index value applicable to the security. Changes is fair value of MBS during each reporting period are recorded in earnings and reported as unrealized gains and losses on mortgage-backed securities in the accompanying consolidated statements of operations.

Retained Interests in Securitizations

From 2005 to 2007, MortCo participated in securitization transactions as part of its mortgage origination business. Retained interests in the subordinated tranches of securities created in securitization transactions were initially recorded at their fair value when issued by MortCo. Subsequent adjustments to fair value are reflected in earnings. Quoted market prices for these assets are generally not available, so the Company estimates fair value based on the present value of expected future cash flows using management's best estimates of key assumptions, which include expected credit losses, prepayment speeds, weighted-average life, and discount rates commensurate with the inherent risks of the asset.

Derivative Financial Instruments

The Company has entered into derivative financial instruments to manage interest rate risk, facilitate asset/liability strategies, and manage other exposures, and it may continue to do so in the future. The Company has elected to not treat any of its derivative financial instruments as hedges. FASB ASC Topic 815, Derivatives and Hedging, requires that all derivative investments be carried at fair value. Changes in fair value are recorded in earnings for each period.

Financial Instruments

FASB ASC Topic 825, Financial Instruments, requires disclosure of the fair value of financial instruments for which it is practicable to estimate that value, either in the body of the financial statements or in the accompanying notes. MBS, Eurodollar futures contracts, mortgage loans held for sale and retained interests in securitization transactions are accounted for at fair value in the consolidated balance sheets. The methods and assumptions used to estimate fair value for these instruments are presented in Note 15 of the financial statements.

The estimated fair value of cash and cash equivalents, restricted cash, accrued interest receivable, repurchase agreements, accrued interest payable and accounts payable and other liabilities generally approximates their carrying value as of December 31, 2012 and December 31, 2011, due to the short-term nature of these financial instruments.

It is impractical to estimate the fair value of the Company's junior subordinated notes. Currently, there is a limited market for these types of instruments and the Company is unable to ascertain what interest rates would be available to the Company for similar financial instruments. Information regarding carrying amount, effective interest rate and maturity date for these instruments is presented in Note 8 to the financial statements.

Property and Equipment, net

Property and equipment, net, consists of computer equipment with a depreciable life of 3 years, office furniture and equipment with depreciable lives of 8 to 20 years, land which has no depreciable life, and buildings and improvements with depreciable lives of 30 years. Property and equipment is recorded at acquisition cost and depreciated using the straight-line method over the estimated useful lives of the assets.

Repurchase Agreements

The Company finances the acquisition of its PT MBS through the use of repurchase agreements. Repurchase agreements are treated as collateralized financing transactions and are carried at their contractual amounts, including accrued interest, as specified in the respective agreements. Although structured as a sale and repurchase obligation, a repurchase agreement operates as a financing under which securities are pledged as collateral to secure a short-term loan equal in value to a specified percentage (generally between 92 and 95 percent) of the market value of the pledged collateral. While used as collateral, the borrower retains beneficial ownership of the pledged collateral, including the right to distributions. At the maturity of a repurchase agreement, the borrower is required to repay the loan and concurrently receive the pledged collateral from the lender or, with the consent of the lender, renew such agreement at the then prevailing financing rate. Margin calls, whereby a lender requires that the Company pledge additional securities or cash as collateral to secure borrowings under its repurchase agreements with such a lender, are routinely experienced by the Company when the value of the MBS pledged as collateral declines or as a result of principal amortization or due to changes in market interest rates, spreads or other market conditions.

The Company's repurchase agreements typically have terms ranging from one month to six months at inception, with some having longer terms. Should a counterparty decide not to renew a repurchase agreement at maturity, the Company must either refinance with another lender or be in a position to satisfy the obligation. If, during the term of a repurchase agreement, a lender should file for bankruptcy, the Company might experience difficulty recovering its pledged assets which could result in an unsecured claim against the lender for the difference between the amount loaned to the Company plus interest due to the counterparty and the fair value of the collateral pledged to such lender including accrued interest and cash posted as collateral. At December 31, 2012, the Company had outstanding balances under repurchase agreements with six lenders with a maximum amount at risk (the difference between the amount loaned to the Company, including interest payable, and the fair value of the collateral pledged by the Company, including accrued interest and cash posted as collateral) of $9.0 million.

Share-Based Compensation

The Company follows the provisions of FASB ASC Topic 718, Compensation – Stock Compensation, to account for stock and stock-based awards. For stock and stock-based awards issued to employees, a compensation charge is recorded against earnings over the vesting period based on the fair value of the award. Payments pursuant to dividend equivalent rights, which are granted along with certain equity based awards, are charged to stockholders' equity when declared. The Company applies a zero forfeiture rate for its equity based awards, as such awards have been granted to a limited number of employees and historical forfeitures have been minimal. A significant forfeiture, or an indication that significant forfeitures may occur, would result in a revised forfeiture rate which would be accounted for prospectively as a change in an estimate. For transactions with non-employees in which services are performed in exchange for the Company's common stock or other equity instruments, the transactions are recorded on the basis of the fair value of the service received or the fair value of the equity instruments issued, whichever is more readily measurable at the date of issuance.

Earnings Per Share

The Company follows the provisions of FASB ASC Topic 260, Earnings Per Share, which requires companies with complex capital structures, common stock equivalents or two (or more) classes of securities that participate in the declared dividends to present both basic and diluted earnings per share (“EPS”) on the face of the consolidated statement of operations. Basic EPS is calculated as income available to common stockholders divided by the weighted average number of common shares outstanding during the period. Diluted EPS is calculated using the “if converted” method for common stock equivalents. However, the common stock equivalents are not included in computing diluted EPS if the result is anti-dilutive.

Outstanding shares of Class B Common Stock, participating and convertible into Class A Common Stock, are entitled to receive dividends in an amount equal to the dividends declared on each share of Class A Common Stock if, as and when authorized and declared by the Board of Directors. Accordingly, shares of the Class B Common Stock are included in the computation of basic EPS using the two-class method and, consequently, are presented separately from Class A Common Stock.

The shares of Class C Common Stock are not included in the basic EPS computation as these shares do not have participation rights. The outstanding shares of Class B and Class C Common Stock are not included in the computation of diluted EPS for the Class A Common Stock as the conditions for conversion into shares of Class A Common Stock were not met.

Reclassifications

Certain prior year amounts have been reclassified to conform to the current year presentations.

Income Taxes

Bimini Capital, including its wholly-owned qualified REIT subsidiary, has elected to be taxed as a REIT under the Code. Bimini Capital will generally not be subject to federal income tax on its REIT taxable income to the extent that Bimini Capital distributes its REIT taxable income to its stockholders and satisfies the ongoing REIT requirements, including meeting certain asset, income and stock ownership tests. A REIT must generally distribute at least 90% of its REIT taxable income to its stockholders, of which 85% generally must be distributed within the taxable year, in order to avoid the imposition of an excise tax. The remaining balance may be distributed up to the end of the following taxable year, provided the REIT elects to treat such amount as a prior year distribution and meets certain other requirements. At December 31, 2012, management believes that the Company has complied with Code requirements and Bimini Capital and its qualified REIT subsidiary continue to qualify as a REIT. As further described in Note 13, Income Taxes, Bimini Advisors and MortCo are taxpaying entities for income tax purposes and are taxed separately from the REIT.

The Company's U.S. federal income tax returns for years ending on or after December 31, 2009 remain open for examination. Although management believes its calculations for tax returns are correct and the positions taken thereon are reasonable, the final outcome of tax audits could be materially different from the tax returns filed by the Company, and those differences could result in significant costs or benefits to the Company.

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-04, Liabilities (Topic 405) - Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date ("ASU 2013-04"). The objective of the amendments in this update is to provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, except for obligations addressed within existing US GAAP. The amendments in ASU 2013-04 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, and should be retrospectively applied to all prior periods presented for those obligations resulting from joint and several liability arrangements within the ASU's scope that exist at the beginning of an entity's fiscal year of adoption. Early adoption is permitted. The Company does not expect that this ASU will have a material impact on its consolidated financial statements.

In January 2013, FASB released ASU 2013-01 Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities, which served solely to clarify the scope of financial instruments included in ASU 2011-11 as there was concern about diversity in practice. The objectives of ASU 2013-01 and ASU 2011-11 are to support further convergence of US GAAP and IFRS requirements. These updates are effective for annual reporting periods beginning on or after January 1, 2013. The Company anticipates that the adoption of this ASU will have no effect on its consolidated financial statements.

In December 2011, the FASB issued ASU 2011-11, Disclosures about Offsetting Assets and Liabilities, requiring improved information about financial instruments and derivative instruments that are either (1) offset in accordance with ASC 210-20-45 or ASC 815-10-45 or (2) subject to an enforceable master netting arrangement. This information will enable users of an entity's financial statements to evaluate the effect or potential effect of netting arrangements on an entity's financial position, including the effect or potential effect of rights of setoff associated with certain financial instruments and derivative instruments in the scope of this ASU. The Company is required to apply the amendments for annual periods beginning on or after January 1, 2013, and interim periods within those annual periods. The disclosures required will be provided retrospectively for all comparative periods presented. The Company anticipates that the adoption of this ASU will have no effect on its consolidated financial statements.

In October 2011, the FASB issued a proposed ASU 2011-20, Financial Services-Investment Companies: Amendments to the Scope, Measurement, and Disclosure Requirements, which would amend the criteria in Topic 946 for determining whether an entity qualifies as an investment company for reporting purposes. As proposed, this ASU would affect the measurement, presentation and disclosure requirements for Investment Companies, as defined, amend the investment company definition in ASC 946, and remove the current exemption for Real Estate Investment Trusts from this topic. If promulgated in its current form, this proposal may result in a material modification to the presentation of the Company's consolidated financial statements. On December 12, 2012, the FASB agreed that the accounting for real estate investments should be considered in a second phase of the Investment Companies project and that all REITs should be exempted from conclusions reached in phase I of the project. The Board has not yet agreed on the scope of phase II of the project. The Company is monitoring developments related to this proposal and is evaluating the effects it would have on the Company's consolidated financial statements.

In June 2011, the FASB issued ASU 2011-05, Presentation of Comprehensive Income, amending the authoritative guidance to allow an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. This ASU eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity, but does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The provisions of this amendment require retrospective application, and are effective for annual and interim periods beginning after December 15, 2011. The adoption of this ASU had no effect on the Company's consolidated financial statements, as the Company has no items of other comprehensive income.

In May 2011, the FASB issued ASU 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, further converging U.S. GAAP and International Financial Reporting Standards (IFRS). The ASU changes the wording used to describe many of the requirements in GAAP for measuring fair value and for disclosing information about fair value measurements to ensure consistency between GAAP and IFRSs as well as expand the disclosures for Level 3 measurements. The ASU is to be applied prospectively, and is effective for annual and interim periods beginning after December 15, 2011. The adoption of this ASU had no effect on the Company's consolidated financial statements.

In April 2011, the FASB issued ASU 2011-03, Reconsideration of Effective Control for Repurchase Agreements, which changes the assessment of whether repurchase agreement transactions should be accounted for as sales or secured financings. In a typical repurchase agreement transaction, an entity transfers financial assets to the counterparty in exchange for cash with an agreement for the counterparty to return the same or equivalent financial assets for a fixed price in the future. Prior to this ASU, one of the factors in determining whether sale treatment could be used was whether the transferor maintained effective control of the transferred assets and in order to do so, the transferor must have the ability to repurchase such assets. Based on this ASU, the FASB concluded that the assessment of effective control should focus on a transferor's contractual rights and obligations with respect to transferred financial assets, rather than whether the transferor has the practical ability to perform in accordance with those rights or obligations. Therefore, this ASU removes the transferor's ability to perform criterion from consideration of effective control. This ASU is effective for the first interim or annual period beginning on or after December 15, 2011. Since the Company records repurchase agreements as secured borrowings and not sales, the adoption of this ASU had no effect on the Company's consolidated financial statements.
